[0036] The dizziness adjustment device, dizziness adjustment method, and dizziness adjustment procedure according to the embodiments will now be described with reference to the accompanying drawings. The following embodiments are merely examples; the embodiments can be appropriately combined and modified. Furthermore, in each figure, the same or identical structures are labeled with the same reference numerals.

[0037] Implementation Method 1

[0038] Figure 1 This diagram illustrates the structure of the dizziness adjustment device 10 according to Embodiment 1 and an example of the image displayed on the display 20. The dizziness adjustment device 10 is an apparatus capable of executing the dizziness adjustment method of Embodiment 1. The dizziness adjustment device 10 is, for example, a computer. The dizziness adjustment device 10 can execute the dizziness adjustment method of Embodiment 1 by executing a dizziness adjustment program. The display 20, which is the display unit for displaying images, is, for example, an HMD, a television, a liquid crystal monitor, or a screen for projecting images from a projector.

[0039] like Figure 1 As shown, the dizziness adjustment device 10 includes a stimulus information generation unit 11, a display control unit 12, and a stimulus information database (stimulus information DB) 13 pre-stored in a storage device. The stimulus information DB 13 does not need to be stored in the storage device that is part of the dizziness adjustment device 10, but can also be stored in an external storage device that can communicate with the dizziness adjustment device 10.

[0040] The stimulus information generation unit 11 generates stimulus information S0 for displaying a dizziness adjustment image (i.e., a stimulus image) 22a on the display 20 to adjust the degree of dizziness experienced by the user 30 viewing the gaze area 21, based on the movement of the gaze object in the area displaying the image containing the gaze object, i.e., the gaze image 21a. For example, the stimulus information generation unit 11 receives image data P0, which forms the basis of the gaze image 21a, and reads stimulus pattern S1 or stimulus effect S2, or both, from the stimulus information DB13 based on the image data P0, and generates stimulus information S0. The stimulus pattern S1 includes, for example, information such as the shape, size, number, and arrangement of the displayed target. The stimulus effect S2 includes one or more of the display conditions such as the movement speed, size, shape, degree of blur, brightness, chroma, and saturation of the displayed dizziness adjustment image 22a. In addition, the stimulus effect S2 may also include the mode of variation of the display conditions.

[0041] The display control unit 12 generates a dizziness adjustment image 22a based on the stimulus information S0, and designates a portion or all of the area of ​​the display 20 that is not the fixation area 21 as the dizziness adjustment area 22, displaying the dizziness adjustment image 22a in the dizziness adjustment area 22. The dizziness adjustment area 22 may be, for example, an area adjacent to the fixation area 21; however, it can also provide a dizziness adjustment effect even when it is not adjacent (e.g., when arranged with intervals). Figure 1 In the image 21a, which includes scenery such as trees, the user moves in the direction of movement D1. The direction D0 of the perceived vection (relative motion illusion) is opposite to the direction of movement D1. Therefore, if the user 30 experiences dizziness due to the movement of the image 21a in the direction of movement D1, the degree of dizziness can be reduced by moving the dizziness-adjusting image 22a, which includes a stimulus pattern, in the same direction of movement D2 as the direction of relative motion illusion D0. Furthermore, the direction of relative motion illusion D0 and the direction of movement D2 of the dizziness-adjusting image 22a do not necessarily need to be the same; however, it is preferable that the direction of relative motion illusion D0 and the direction of movement D2 of the dizziness-adjusting image 22a are the same.

[0042] Figure 2 This is a diagram illustrating an example of the hardware structure of the dizziness adjustment device 10 according to Embodiment 1. (See diagram below.) Figure 2 As shown, the dizziness adjustment device 10 includes a processor 101 such as a CPU (Central Processing Unit), a memory 102 as a volatile storage device, and a non-volatile storage device 103 such as a hard disk drive (HDD) or a solid-state drive (SSD). The memory 102 is, for example, a volatile semiconductor memory such as RAM (Random Access Memory). The dizziness adjustment device 10 has an interface 104.

[0043] The various functions of the dizziness adjustment device 10 are implemented through a processing circuit. The processing circuit can be dedicated hardware or a processor 101 that executes programs stored in the memory 102. The processor 101 can be any of a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor).

[0044] When the processing circuit is dedicated hardware, the processing circuit may be a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

[0045] When the processing circuit is processor 101, the vertigo adjustment program is implemented through software, firmware, or a combination of both. The software and firmware are described as programs and stored in memory 102. Processor 101 reads and executes the vertigo adjustment program stored in memory 102, thereby achieving... Figure 1 The functions of each part are shown.

[0046] Alternatively, the dizziness adjustment device 10 can be partially implemented using dedicated hardware and partially using software or firmware. In this way, the processing circuitry can implement the aforementioned functions through hardware, software, firmware, or any combination thereof.

[0047] Figure 3 It is used for explanation Figure 1 A diagram illustrating the motion of the images (including fixation image 21a and dizziness adjustment image 22a) displayed on the monitor 20. (See diagram 22a for details.) Figure 3 As shown, Figure 1 The gaze image 21a displayed on the monitor 20 corresponds to the scenery when a user 30 wearing a monitor with a central opening in front of their face turns left from the same position to change their body orientation. The direction of the relative motion illusion, D0, is opposite to the direction of movement of the scenery, D1.

[0048] Figure 4 It is shown Figure 1 A diagram illustrating an example of motion of an image displayed on monitor 20. Figure 4The images displayed on the monitor 20 include a fixation image 21a displayed in a fixation area 21 near the center, and a dizziness adjustment image 22a displayed in a dizziness adjustment area 22 adjacent to the fixation area 21. The fixation image 21a is an image based on input image data P0. The dizziness adjustment image 22a is a stimulus image generated based on stimulus information S0. Figure 4 As shown, user 30 feels (i.e., has an illusion) that he is moving in direction D0. Therefore, by moving the background portion of the gaze image 21a, i.e. the dizziness adjustment image 22a, in the same direction as the direction of the relative motion illusion D0, i.e. the movement direction D2, the degree of dizziness of user 30 can be reduced.

[0049] Figure 5 This is a flowchart illustrating the operation of the dizziness adjustment device 10 according to Embodiment 1. First, after receiving image data P0 (step ST11), the dizziness adjustment device 10 reproduces the gaze image (also called "flow information") 21a displayed in the gaze area 21 (step ST12). The dizziness adjustment device 10 analyzes the gaze image 21a (step ST13) and determines whether it is necessary to display the dizziness adjustment image 22a (step ST14). For example, the determination of whether it is necessary is based on information obtained in advance through testing that indicates the relationship between the movement speed of the gaze image and the degree of dizziness of the user viewing the gaze image.

[0050] If it is not necessary to display the dizziness adjustment image (step ST15: No), the dizziness adjustment device 10 generates depiction data without the dizziness adjustment image and outputs it to the display 20 (step ST18).

[0051] When it is necessary to display a dizziness adjustment image (step ST15: Yes), the dizziness adjustment device 10 sets the effect of the stimulus information (step ST16), generates stimulus information with reference to the stimulus information DB (step ST17), generates depiction data with the dizziness adjustment image, and outputs it to the display 20 (step ST18). As a result, for example, the image is displayed on the display 20. Figure 4 The image shown is obtained by combining the fixation image 21a and the dizziness adjustment image 22a.

[0052] As explained above, if the dizziness adjustment device 10, dizziness adjustment method or dizziness adjustment procedure of Embodiment 1 is used, the user 30 can reduce the degree of dizziness by moving the background of the gaze image 21a, i.e., the dizziness adjustment image 22a, in the same direction as the direction of relative motion illusion D0 (i.e., the opposite direction of the movement direction D1 of the gaze image 21a), i.e., the movement direction D2.

[0053] Figure 6Figures (A) to (C) are the first example of how the dizziness adjustment image 22a appears (i.e., an example of gradually changing the transmittance of the dizziness adjustment image). Figure 6 (A) shows the state where the dizziness adjustment image 22a has the highest transmittance (approximately 100%) and is almost impossible to see (visually see the image based on image data P0). Figure 6 (B) shows the state of the dizziness adjustment image 22a with reduced transmittance (transmittance of about 50%) and the ability to see both the background image and the dizziness adjustment image 22a on the front side. Figure 6 (C) shows that the transmittance of the dizziness adjustment image 22a is approximately 0% and the state of the dizziness adjustment image 22a can only be viewed visually.

[0054] like Figure 6 As shown in (A) to (C), in the first example of the appearance mode of the dizziness adjustment image 22a, the display control unit 12 gradually decreases the transmittance of the dizziness adjustment image 22a from a high value to a low value at the beginning of the display of the dizziness adjustment image 22a. Therefore, the appearance of the dizziness adjustment image 22a is not easily noticed by the user 30, and the user 30 is not likely to notice the dizziness adjustment image 22a. In addition, if the disappearance mode of the dizziness adjustment image 22a is as follows... Figure 6 (C) Figure 6 (B) Figure 6 If the process is performed in the order of (A) (i.e., the reverse order of appearance), the user 30 will not easily notice the dizziness adjustment image 22a. Alternatively, the display control unit 12 can perform a process that changes the transmittance of the dizziness adjustment image at the end of its display, in addition to the process that changes the transmittance of the dizziness adjustment image at the start of its display. Furthermore, the display control unit 12 can perform a process that changes the transmittance of the dizziness adjustment image at the end of its display, instead of the process that changes the transmittance of the dizziness adjustment image at the start of its display.

[0055] Figure 7 (A) to (C) are the second example of how the dizziness adjustment image 22a appears (i.e., an example of gradually changing the size of the gaze area 21). Figure 7 (A) shows the state where the size of the gaze area 21 is large (i.e., the area of ​​the dizziness adjustment area 22 is small). Figure 7 (B) shows that the size of the gaze area 21 is moderate (i.e., the area of ​​the dizziness adjustment area 22 is slightly larger). Figure 7 (C) shows the state where the size of the gaze area 21 is at its minimum (i.e., the area of ​​the dizziness adjustment area 22 is at its maximum).

[0056] like Figure 7As shown in (A) to (C), in the second example of the appearance mode of the dizziness adjustment image 22a, the display control unit 12 gradually reduces the size of the gaze area 21 from a large value to a small value when the dizziness adjustment image 22a is displayed. Therefore, the appearance of the dizziness adjustment image 22a is not easily noticed by the user 30, and the user 30 is not likely to notice the dizziness adjustment image 22a. Furthermore, if the disappearance mode of the dizziness adjustment image 22a is as follows... Figure 7 (C) Figure 7 (B) Figure 7 If the process is carried out in the order of (A) (i.e., the reverse order of the appearance), then the user 30 will not easily notice the dizziness adjustment image 22a.

[0057] That is, the display control unit 12 performs at least one of the following processes: when the display of the dizziness adjustment image begins, the size of the gaze area 21 is gradually reduced from a large value to a small value; and when the display of the dizziness adjustment image ends, the size of the gaze area 21 is gradually increased from a small value to a large value. This allows the dizziness to be adjusted.

[0058] Furthermore, the display control unit 12 performs at least one of the following processes: gradually increasing the size of the gaze area 21 from a small value to a large value when the display of the dizziness adjustment image begins and gradually decreasing the size of the gaze area 21 from a large value to a small value when the display of the dizziness adjustment image ends, thereby adjusting the dizziness effect.

[0059] Figure 8 (A) and (B) are the third example of how the dizziness adjustment image 22a appears (i.e., an example in which the dizziness adjustment image 22a gradually changes from a gray image to a striped pattern image). Figure 8 (A) shows the state of the dizziness adjustment area 22 for monochrome images (e.g., low brightness or low density gray images) that are not easily noticed by the user 30. Figure 8 (B) shows the state where the brightness of the dizziness adjustment image 22a in the dizziness adjustment area 22 increases or the density of the stripe pattern gradually increases, eventually displaying the dizziness adjustment image 22a (i.e., the area of ​​the dizziness adjustment area 22 is at its maximum).

[0060] like Figure 8 As shown in (A) and (B), in the third example of the appearance mode of the dizziness adjustment image 22a, the display control unit 12 initially makes the dizziness adjustment image 22a a single, inconspicuous color, gradually increasing the intensity until a striped pattern appears. Therefore, the appearance of the dizziness adjustment image 22a is not easily noticed by the user 30, and the user 30 is unlikely to notice the dizziness adjustment image 22a. Furthermore, if the disappearance mode of the dizziness adjustment image 22a is as follows... Figure 8 (B) Figure 8If the process is carried out in the order of (A) (i.e., the reverse order of the appearance), then the user 30 will not easily notice the dizziness adjustment image 22a.

[0061] That is, by performing at least one of the following processes—gradually increasing the brightness of the dizziness adjustment image from a low value to a high value at the start of displaying the dizziness adjustment image and gradually decreasing the brightness of the dizziness adjustment image from a high value to a low value at the end of displaying the dizziness adjustment image—dizziness can be reduced. Furthermore, by performing at least one of the following processes—gradually decreasing the brightness of the dizziness adjustment image from a high value to a low value at the start of displaying the dizziness adjustment image and gradually increasing the brightness of the dizziness adjustment image from a low value to a high value at the end of displaying the dizziness adjustment image—the dizziness effect can be enhanced.

[0062] Alternatively, the display control unit 12 may perform at least one of the following processes: gradually increasing the density of the dizziness adjustment image from a low value to a high value at the start of displaying the dizziness adjustment image, and gradually decreasing the density of the dizziness adjustment image from a high value to a low value at the end of displaying the dizziness adjustment image, thereby reducing dizziness. Furthermore, the display control unit 12 may perform at least one of the following processes: gradually decreasing the density of the dizziness adjustment image from a high value to a low value at the start of displaying the dizziness adjustment image, and gradually increasing the density of the dizziness adjustment image from a low value to a high value at the end of displaying the dizziness adjustment image, thereby enhancing the dizziness effect.

[0063] Figure 9 (A) and (B) are the fourth example of how the dizziness adjustment image appears (i.e., an example in which the movement speed of the dizziness adjustment image gradually increases from a stationary state). Figure 9 (A) shows the dizziness adjustment image 22a in a stopped state that is not easily noticed by the user 30. Figure 9 (B) shows the state of the dizziness adjustment image 22a of the dizziness adjustment area 22 moving in the movement direction D2.

[0064] like Figure 9 As shown in (A) and (B), in the fourth example of the display method of the dizziness adjustment image 22a, the display control unit 12 stops the dizziness adjustment image 22a at the beginning of its display and gradually increases the movement speed in the movement direction D2, eventually reaching the speed specified by the stimulus information S0 generated by the stimulus information generation unit 11. Therefore, the start of the movement of the dizziness adjustment image 22a is not easily noticed by the user 30, and the user 30 is not likely to notice the dizziness adjustment image 22a. Furthermore, if the stopping method of the movement of the dizziness adjustment image 22a is in accordance with... Figure 9 (B) Figure 9If the process is performed in the order of (A) (i.e., the reverse order of the starting method of movement), the user 30 will not easily notice the dizziness adjustment image 22a. That is, if the display control unit 12 performs at least one of the processes of gradually increasing the movement speed of one or more targets at the beginning of the display of the dizziness adjustment image and gradually decreasing the movement speed of one or more targets at the end of the display of the dizziness adjustment image, dizziness can be reduced.

[0065] Figure 10 (A) and (B) are the fifth example of how the dizziness adjustment image 22a appears (i.e., an example in which the dizziness adjustment image 22a gradually becomes more blurred from a clear state). Figure 10 (A) shows a dizziness adjustment image 22a that is clear and in a state that is not easily noticed by the user 30. Figure 10 (B) shows the state in which the dizziness adjustment image 22a of the dizziness adjustment area 22 becomes blurred.

[0066] like Figure 10 As shown in (A) and (B), in the fifth example of the appearance mode of the dizziness adjustment image 22a, the display control unit 12 makes the dizziness adjustment image 22a clear but inconspicuous at the beginning of its display, gradually increasing the degree of blurring, and finally achieving the blur specified by the stimulus information S0 generated by the stimulus information generation unit 11. Therefore, the appearance of the dizziness adjustment image 22a is not easily noticed by the user 30 at the beginning, and the user 30 is not likely to notice the dizziness adjustment image 22a. Furthermore, if the disappearance mode of the dizziness adjustment image 22a is in accordance with... Figure 10 (B) Figure 10 If the process is carried out in the order of (A) (i.e., the reverse order of the appearance), then the user 30 will not easily notice the dizziness adjustment image 22a.

[0067] That is, the display control unit 12 performs at least one of the following processes: at the beginning of the display of the dizziness adjustment image, the blur level of the dizziness adjustment image is gradually increased from a low value to a high value, and at the end of the display of the dizziness adjustment image, the blur level of the dizziness adjustment image is gradually decreased from a high value to a low value, thereby adjusting the dizziness effect.

[0068] Furthermore, the display control unit 12 performs at least one of the following processes: at the beginning of the display of the dizziness adjustment image, the blur level of the dizziness adjustment image is gradually reduced from a high value to a low value, and at the end of the display of the dizziness adjustment image, the blur level of the dizziness adjustment image is gradually increased from a low value to a high value, thereby adjusting the dizziness effect.

[0069] Figure 11Figures (A) to (C) are illustrations of another example of an image displayed on a monitor (an example of a quadrilateral viewing area). Figure 11 (A) shows a case where the gaze area 21 is located in the center of the image and a dizziness adjustment area 22 is formed in the adjacent position around it. Figure 11 (B) shows a case where the gaze area 21 is located in the center of the left-right direction of the screen and a dizziness adjustment area 22 is formed in the adjacent left and right positions around it. Figure 11 (C) shows a case where the gaze area 21 is located in the center of the vertical direction of the image, and dizziness adjustment areas 22 are formed in adjacent vertical positions around it. Furthermore, Figure 11 (C) shows an example where the stimulus pattern constituting the dizziness adjustment image 22a is a pattern of multiple moving dots. Figure 11 As shown in (A) to (C), the shape of the gaze region 21 can also be a quadrilateral. In addition, the shape of the gaze region 21 can also be a shape other than a circle, an ellipse, or a quadrilateral.

[0070] Figure 12 (A) and (B) are diagrams showing another example (water droplets and butterflies) of the target 23 constituting the dizziness adjustment image 22a. As shown, the dizziness adjustment image 22a can also be composed of a stimulus pattern with multiple water droplets or multiple butterflies as the target 23. In this way, the target 23 constituting the stimulus pattern can also not be a geometric shape, but a shape that simulates the shape of substances, animals, plants, etc. that exist in nature.

[0071] Furthermore, the above explanation illustrates an example where the movement direction D2 of the dizziness adjustment image 22a is horizontal; however, it is not limited to the horizontal direction. The movement direction D2 can be determined based on the movement direction D1 of the fixation image 21a.

[0072] Implementation Method 2

[0073] In Embodiment 1, an example of displaying a gaze image 21a in the gaze area 21 is described. In Embodiment 2, an example of a user 30 viewing a real moving object (e.g., a real landscape) in the gaze area 21 is described.

[0074] Figure 13This diagram illustrates the structure of the dizziness adjustment device 10a according to Embodiment 2 and an example of an image displayed (i.e., projected) on the windshield 40 of the vehicle 41. The dizziness adjustment device 10a is an apparatus capable of executing the dizziness adjustment method of Embodiment 2. The dizziness adjustment device 10a is, for example, a computer. By executing a dizziness adjustment program, the dizziness adjustment device 10a can execute the dizziness adjustment method of Embodiment 2. In addition, the dizziness adjustment device 10a can also be applied to AR glasses, etc., for superimposing actual scenery and augmented reality (AR) images. Furthermore, the dizziness adjustment device 10a can replace the windshield or, based on the windshield, display or project dizziness adjustment images onto in-vehicle displays (e.g., displays showing car navigation images, rear displays, center displays, etc.), dashboard panels, vehicle hoods, pillars, or ceilings. In this way, by expanding the display area of ​​the dizziness adjustment images, dizziness can be effectively adjusted not only for the driver but also for passengers other than the driver.

[0075] like Figure 13 As shown, the dizziness adjustment device 10a includes a stimulus information generation unit 11, a display control unit 12, and stimulus information DB13 pre-stored in a storage device. The stimulus information DB13 does not need to be part of the dizziness adjustment device 10a, and can also be stored in an external storage device that can communicate with the dizziness adjustment device 10a. The stimulus information generation unit 11 generates stimulus information S0 for adjusting the degree of dizziness caused to the user 30 viewing the viewing area 21 by displaying a dizziness adjustment image (i.e., a stimulus image) 22a on the display 20 to adjust the degree of dizziness caused to the user 30 viewing the viewing area 21 based on the movement of the object being viewed in the area displaying the image containing the object being viewed, i.e., the viewing image 21a.

[0076] The display control unit 12 generates a dizziness adjustment image 22a based on the stimulus information S0, and displays the dizziness adjustment image 22a in the dizziness adjustment area 22 of the display 20 adjacent to the fixation area 21. Figure 13 In the image 21a, which contains scenery such as trees, the image moves in the direction of movement D1. In this case, the direction of relative motion illusion D0 is the opposite direction of the scenery's movement direction D1.

[0077] Therefore, when user 30 experiences dizziness due to the movement of the scenery in the direction D1, the degree of dizziness can be reduced by moving the dizziness adjustment image 22a containing the stimulus pattern in the same direction D2 as the direction of relative motion illusion D0. Furthermore, the direction D0 of relative motion illusion and the direction D2 of dizziness adjustment image 22a do not necessarily need to be the same; however, it is preferable that the direction D0 of relative motion illusion and the direction D2 of dizziness adjustment image 22a are the same.

[0078] Figure 14This is a diagram illustrating an example of the hardware structure of the dizziness adjustment device 10a according to Embodiment 2. Figure 14 In the middle, to and Figure 2 The structural elements shown are the same as or correspond to the structural element labels. Figure 2 The labels shown are the same. Figure 14 Structure and Figure 2 The difference in structure lies in the presence of a camera 43 that captures images of the front of the vehicle 41 and a projector 42. The camera image P1 captured by the camera 43 is provided to the stimulus information generation unit 11, which generates stimulus information S0 based on the camera image P1. The projector 42 projects a stimulus pattern onto the windshield 40, for example.

[0079] Figure 15 It is used to illustrate the passage Figure 13 The diagram shows the motion of the real scenery viewed through the windshield 40 and the motion of the dizzying adjusted image displayed on the windshield. (By...) Figure 13 The viewing area 21 seen through the windshield 40 corresponds to the scenery viewed by a user 30 wearing a centrally positioned display in front of their face while moving along a road. The direction of the relative motion illusion, D0, is opposite to the direction of movement of the scenery, D1.

[0080] As explained above, if the dizziness adjustment device 10a, dizziness adjustment method or dizziness adjustment procedure of Embodiment 2 are used, the user 30 can reduce the degree of dizziness by moving the background of the gaze image 21a, i.e., the dizziness adjustment image 22a, in the same direction as the direction of relative motion illusion D0 (i.e., the opposite direction of the movement direction D1 of the gaze image 21a), i.e., the movement direction D2.

[0081] Figure 16 (A) and (B) are shown by Figure 13 The diagram shows another example of the movement of the real scenery viewed through the windshield 40 (movement direction D1) and the movement of the dizzying adjusted image 22b displayed (e.g., projected) on the windshield 40 (when the vehicle 41 is moving forward). Figure 16 (A) shows the passage through Figure 13 The motion (movement direction D1) of the real scenery viewed through the windshield 40 and the circular target 23 constituting the dizziness-adjusting image 22b displayed (e.g., projected) on the windshield 40. Figure 16 (B) shows the passage Figure 13 The motion (movement direction D1) of the real scenery viewed through the windshield 40 and the larger circular target 23 constituting the dizzying pattern of the stimulating image 22b displayed (e.g., projected) on the windshield 40.

[0082] like Figure 16 As shown in (A) and (B), if the dizziness adjustment device 10a, dizziness adjustment method, or dizziness adjustment procedure of Embodiment 2 is used, the user 30 can reduce the degree of dizziness by changing the background of the gaze area 21, i.e., the dizziness adjustment image 22b, according to the direction D0 of the relative motion illusion (i.e., changing the size of the target 23). That is, the display control unit 12 can adjust the degree of dizziness by performing at least one of the following processes: gradually increasing or decreasing the size of one or more targets at the beginning of the display of the dizziness adjustment image and gradually decreasing or increasing the size of one or more targets at the end of the display of the dizziness adjustment image.

[0083] Figure 17 (A) and (B) are shown by Figure 13 The diagram shows another example of the motion of the real scenery viewed through the windshield 40 and the motion of the dizzying adjusted image displayed on the windshield 40 (when the vehicle is turning left). Figure 17 (A) shows the passage through Figure 13 The motion (movement direction D1) of the real scenery viewed through the windshield 40 and the circular target 23 constituting the dizziness-adjusting image 22b displayed (e.g., projected) on the windshield 40. Figure 17 (B) shows the passage Figure 13 The moving real scenery seen through the windshield 40 (vehicle 41 turning left) and the circular target 23 constituting the dizziness-adjusting image 22b displayed on the windshield 40.

[0084] like Figure 17 As shown in (A) and (B), if the dizziness adjustment device 10a, dizziness adjustment method, or dizziness adjustment procedure of Embodiment 2 is used, the target 23 is distributed across the entire area of ​​the windshield 40 during straight-line movement of the vehicle 41; during left turns, the target 23 is concentrated on the left side of the windshield 40; and during right turns, the target 23 is concentrated on the right side of the windshield 40. Thus, by changing the arrangement of the target 23 according to the direction D0 of the relative motion illusion, the degree of dizziness experienced by the user 30 can be reduced.

[0085] Implementation Method 3

[0086] In Embodiment 1, an example of generating a dizziness adjustment image 22a based on the gaze image 21a was described. In Embodiment 3, an example of generating a dizziness adjustment image 22a using the gaze image 21a and the dizziness characteristics of the user 30 was described. Furthermore, in Embodiment 3, its use for enhancing the dizziness tolerance of the user 30 was also described.

[0087] Figure 18This diagram illustrates the structure of the dizziness adjustment device 10b according to Embodiment 3. The dizziness adjustment device 10b is an apparatus capable of executing the dizziness adjustment method of Embodiment 3. The dizziness adjustment device 10b is, for example, a computer. By executing a dizziness adjustment program, the dizziness adjustment device 10b can execute the dizziness adjustment method of Embodiment 3. Similar to the case of Embodiment 1, the drawing data output from the dizziness adjustment device 10b is output to the display 20.

[0088] like Figure 18 As shown, the dizziness adjustment device 10b includes a stimulus information generation unit 11, a display control unit 12b, stimulus information DB13, a dizziness determination unit 14, a test dynamic image DB15, and an individual's dizziness characteristics DB16. The test dynamic image DB15 and the individual's dizziness characteristics DB16 do not need to be stored in a storage device that is part of the dizziness adjustment device 10b, but can be stored in an external storage device that can communicate with the dizziness adjustment device 10b.

[0089] Test motion image DB15 is a database of test motion images displayed to users when determining the dizziness characteristics of each user (i.e., each individual). Dizziness characteristic DB16 is a database of individual dizziness characteristics determined when users view the test motion images.

[0090] The dizziness determination unit 14 performs the process of determining the user's dizziness characteristics and storing them in the dizziness characteristic DB16, and provides the corresponding user's dizziness characteristic information to the display control unit 12b when a user is identified. The dizziness determination unit 14 determines dizziness based on the results obtained from measuring the user's physical information or the user's self-report (i.e., self-evaluation of the degree of dizziness).

[0091] The display control unit 12b generates a dizziness adjustment image 22a based on the stimulus information S0 and the individual's dizziness characteristics stored in the dizziness characteristics DB16, and displays the dizziness adjustment image (i.e., the stimulus image) 22a in the dizziness adjustment area 22.

[0092] Figure 19 This is a flowchart illustrating the operation of the dizziness adjustment device 10b according to Embodiment 3. The dizziness adjustment device 10b first displays a test dynamic image on the display, determines the dizziness characteristics of each person (steps ST31, ST32), and stores the dizziness characteristics in the dizziness characteristic DB16 (step ST33).

[0093] When generating the depiction data, the dizziness adjustment device 10b receives the image data P0, the user's individual dizziness characteristics, and the purpose of dizziness adjustment (step ST11a), and then reproduces the gaze image (motion information) displayed in the gaze area (step ST12a). The dizziness adjustment device 10b analyzes the gaze image displayed in the gaze area (step ST13), and determines whether it is necessary to display a dizziness adjustment image based on the analysis results, the individual's dizziness characteristics, and the purpose of adjustment (step ST14a).

[0094] If it is not necessary to display the dizziness adjustment image (step ST15: No), the dizziness adjustment device 10b generates depiction data without the dizziness adjustment image and outputs it to the display 20 (step ST18).

[0095] When it is necessary to display a dizziness adjustment image (step ST15: Yes), the dizziness adjustment device 10b sets the effect of the stimulus information according to the analysis results, the individual's dizziness characteristics and the purpose of adjustment (step ST16a), generates stimulus information with reference to the stimulus information DB (step ST17), generates depiction data with dizziness adjustment image, and outputs it to the display 20 (step ST18).

[0096] Figure 20 Figures (A) to (C) are examples of images displayed on the display of the dizziness adjustment device 10b according to Embodiment 3. Figure 20 (A) shows the state of the dizziness adjustment image 22a displayed in order to suppress or promote dizziness caused by the gaze image 21a. Figure 20 (B) shows the situation where the movement speed V2 of the dizziness adjustment image 22a is adjusted in order to adjust the effect of suppressing or promoting dizziness caused by the gaze image 21a when the movement direction D1 of the gaze image 21a is opposite to the movement direction D2 of the dizziness adjustment image 22a. Figure 20 (C) shows the situation where the movement speed V2a of the dizziness adjustment image 22a is adjusted in order to adjust the effect of suppressing or promoting dizziness when the movement direction D1 of the gaze image 21a is the same as the movement direction D2a of the dizziness adjustment image 22a.

[0097] exist Figure 20 In (C), without dizziness occurring due to the movement of the gaze image 21a alone, when a dizziness adjustment image 22a is displayed together with the gaze image 21a, and the speed V2a of the dizziness adjustment image 22a is faster than the speed V1 of the gaze image 21a (i.e., V2a > V1), a dizziness-enhancing effect (i.e., an effect that strengthens realism) is obtained. Furthermore, in Figure 20In (C), when dizziness is caused by the movement of the fixation image 21a alone, the dizziness adjustment image 22a is displayed together with the fixation image 21a, and when the speed V2a of the dizziness adjustment image 22a is slower than the speed V1 of the fixation image 21a (i.e., when V2a < V1), the effect of reducing the occurrence of dizziness (i.e., the effect of adjusting the sense of reality) is obtained. Using Figure 20 The device having the effects shown in (A) to (C) can adjust the effect of suppressing or promoting dizziness, and thus is useful for the intensive training of the user 30's dizziness tolerance.

[0098] As described above, if the dizziness adjustment device 10b, the dizziness adjustment method, or the dizziness adjustment program of Embodiment 3 is used, the user 30 can reduce the degree of dizziness of the user 30 by moving the background of the fixation image in the moving direction D2 that is the same as the direction D0 of the relative motion illusion.

[0099] In addition, when aiming at strengthening the user's dizziness tolerance, the degree of dizziness of the user 30 can be increased by moving the background of the fixation image in the direction D2a that is opposite to the direction D0 of the relative motion illusion.
